[Python-Dev] violently deprecating exec without in (was: nested scopes. global: have I got it right?)

At the top-level, there is no closure created by the enclosing scope
is not a function scope.  I believe that's the right thing to do,
except that the exec "x=3" also assign to the global.

I'm not sure if there is a strong justification for allowing this
form, except that it is the version of exec that is most likely to
occur in legacy code.
